Bypassing ABS on the rear only early ABS does not affect proportion. Those ABS pumps only break pressure in the line. Prop valve works the same either way. I'm sure the later OBS worked the same way.

1. WHAT VEHICLE???So I'm deleting the abs on my truck
Didn't the '93 have a separate combination valve before the ABS. I'd use that or buy a combination valve for disc/disc or disc/drum.
T'ing up the front to the master cylinder seems a little rigged. You don't have the benefit of the front metering system found in the combination valve. The slightly delayed front brake apply from the metering is going to help keep the ass end of the truck from sliding out when the fronts grab first in panic because it was T'd to the MC. Even ABS package in the '96 was routed after the combination valve in the brake system.
With the combination valve there's already two ports on it for the front wheels and one for the rear. Or you can block a front port, use one, then T. It has the metering valve already to allow the rear brakes to contact before the front wheels, the limp mode piston to block fluid direction if the front or rear were to spring a leak, the dummy light switch, and the rear proportioning valve to limit rear pressure if the brakes are slammed. The can be bought for both disc/disc setup or disc/drum
I like this ABS delete because he put in the combination valve.
